The New South Wales (NSW) government will introduce legislation on Tuesday making it a criminal offence to secretly monitor a person using GPS or surveillance devices without their knowledge, where a reasonable person would consider such conduct likely to cause fear of physical or mental harm. The move follows a 2024 NSW Crime Commission report — Project Hakea — which found that tracking devices were increasingly being weaponised by domestic violence perpetrators, and estimated that one in four buyers of such devices in the state had a history of domestic violence. The reforms also introduce new offences for directing a third party to stalk someone on another's behalf, and for advertising surveillance devices in ways that encourage unlawful use, as part of a broader push by the state government to modernise laws it says have failed to keep pace with technology-enabled abuse.
